Foton 704 steering issue

It sounds like you are on the right track.

Just to be clear, the wheels going straight happens while driving, right?

One test for the cylinder on the axle is to remove the hoses and plug off the ends, making sure to keep as much oil in the cylinder as possible. Then jack both wheels off of the ground and see if you can make the wheels turn from side to side using hand pressure on the tires. If they easily turn it might indicate an internal leak in the cylinder.

If they turn but spring back, it is probably just air in the cylinder.

Best of luck and let us know what you find.

I am kinda leaning at the steering cylinder as when the steering wheel turning is sending fluid to the cylinder it goes where you want it to go, when the fluid is stopped being sent it stops steering. so That is what makes me think the cylinder is bypassing. Of course I easily could be wrong. The cylinder would be also the much easier fix to do lets hope that is the problem. keep us informed as to what you find as I have a foton 504a so info. is always good to know.
